Element RC has listened to the demands of the RC community and delivered a conversion kit that meets the highest standards for quality, durability and performance. These portal axles are engineered with all metal gears, ball bearings, and an upgraded larger pocket for a heavier-duty inner input bearing, ensuring longevity and reliability even under the most demanding trail conditions. The kit is designed as a direct replacement for most 1/10 scale crawlers and trail trucks, making it an accessible upgrade for owners of compatible Element RC Enduro models.

If you're searching for quality RC car upgrades UK-wide, or you're looking to enhance your ready to run RC crawler with professional-grade components, the Enduro Portal Axle Conversion Kit delivers exactly what experienced bashers and competitors expect. This is not just a cosmetic upgrade—it's a functional transformation that genuinely improves your vehicle's capability on rock gardens, natural terrain, and technical trails.

Key Features

• High Clearance Design — With almost an inch of additional centre axle clearance compared to standard straight axles, this kit allows your RC crawler to glide over obstacles that would otherwise cause ground contact issues, giving you significantly improved approach and departure angles for extreme terrain.
• Universal Axle Configuration — These portal axles offer exceptional versatility, functioning as front axles with behind-the-axle steering in either servo-on-axle or chassis-mounted servo setups, as rear axles with adjustable rear toe lockouts, or even as a rear steer axle for the ultimate hardcore rock crawling rig configuration.
• All Metal Construction — Every gear throughout the axles is metal, paired with 24 metal ball bearings and steel pivot balls, ensuring durability and long service life even during intensive use on rocky terrain and technical courses.
• Enhanced Input Bearing Support — The larger inner input bearing pocket is now standard across all Enduro axles, providing additional support and distributing stress more effectively during extreme articulation and load conditions.
• Adjustable Caster and Toe — The adjustable caster geometry and rear toe lockouts allow you to fine-tune your vehicle's handling characteristics to match your specific driving style and the terrain you frequent most.
• Aluminium Steering Plates — High-quality aluminium steering plates reduce unsprung weight whilst maintaining structural integrity, improving overall vehicle responsiveness and reducing suspension stress.
• Compatible with Multiple Servo Setups — Whether you prefer chassis-mounted or axle-mounted servo configurations, this kit accommodates both installation styles, providing flexibility for custom builds and different steering geometries.
• Optional Gear Ratios Available — The separately available 12/23 gear set offers approximately 36% underdrive for serious rock crawler addicts who want maximum low-end torque for extreme crawling applications.

Technical Performance

The Element RC Enduro Portal Axle Conversion Kit represents a pinnacle of RC crawler engineering, combining advanced materials science with proven portal axle design principles used in full-size four-wheel-drive vehicles. The all-metal gear construction throughout the axle assembly ensures smooth power transmission and resilience against the impact loads generated when navigating rocky, technical terrain. With 24 metal ball bearings integrated throughout the assembly, this kit distributes forces evenly and minimises friction, resulting in smooth operation and improved efficiency compared to standard plastic-geared alternatives. The larger pocket for the heavier-duty inner input bearing increases the contact patch and load-carrying capacity, crucial for vehicles that encounter high-stress situations during competitive events or wilderness expeditions. The adjustable caster and rear toe settings allow you to optimise your vehicle's geometry for specific terrains—tighter caster angles for tighter turns, or more aggressive angles for improved stability on loose surfaces. The construction utilises both steel components for strength and aluminium elements for weight reduction, creating an optimal balance between durability and performance. These axles are engineered as direct replacements for most 1/10 scale crawlers and trail trucks, making installation straightforward for experienced RC enthusiasts with basic mechanical aptitude and standard hex drivers.

Frequently Asked Questions

• Which Element RC Enduro models is this portal axle kit compatible with? — The EL40128 conversion kit is compatible with the Element RC Enduro Ecto Trail Truck RTR (Green, Black), Element RC Enduro Trail Truck Zuul Tan RTR, Element RC Enduro Ecto Trail Truck RTR Grey (which comes with portal axles already installed), Element RC Enduro Trailwalker RTR (Black), Element RC Enduro Trail Truck Sendero HD RTR (Black), Element RC Enduro Sendero HD Titanium RTR, and the Element RC Enduro Trail Truck Knightwalker (Red RTR). Check your model number against this list to confirm compatibility before ordering.
• How much clearance improvement do these portal axles provide? — These portal axles provide almost an inch of additional centre axle clearance compared to Element RC's standard straight axles. This extra clearance is crucial for serious rock crawling, allowing you to maintain ground clearance when driving over obstacles, ledges, and technical terrain that would otherwise cause your vehicle's chassis to scrape.
• Can I use different gear ratios with this kit? — Yes, the portal axle kit uses replaceable gears. Whilst the standard ratio comes installed, you can separately purchase the 12/23 gear set, which offers approximately 36% underdrive. This reduced ratio is ideal for serious rock crawler addicts who prioritise maximum low-end torque and climbing ability over top speed, making it perfect for technical competition courses.
• What servo mounting options does this kit support? — This kit is fully compatible with both chassis-mounted servo and axle-mounted servo setups. You can configure the front axle with behind-the-axle steering in either arrangement, use it as a rear axle with adjustable rear toe lockouts, or even as a rear steer axle for ultimate hardcore rock crawling configurations. This versatility allows you to build the vehicle setup that best matches your driving style and competition requirements.
• Is this kit suitable for beginners, or only for experienced crawlers? — Whilst this is a conversion kit rather than a plug-and-play upgrade, it requires basic mechanical ability and the correct tools (2.0 mm and 1.5 mm hex drivers). If you have experience assembling or modifying RC vehicles, this conversion is well within reach. However, beginners without mechanical experience may benefit from seeking assistance or guidance during installation. The engineering quality is such that once installed correctly, maintenance and operation are straightforward.
• What tools do I need to install this portal axle kit? — You'll need two specific tools: a 2.0 mm hex driver (Element RC part AS1501) and a 1.5 mm hex driver (Element RC part AS1500). Most experienced RC enthusiasts already have hex drivers in these sizes as part of their standard RC toolkit. These are standard metric drivers widely available from hobby shops across the UK.
• How does the upgraded inner input bearing benefit my crawler? — The larger inner input bearing pocket that's now standard on all Enduro axles provides enhanced support and improved stress distribution during articulation. This means better durability during technical driving, improved longevity of the axle assembly, and reduced likelihood of bearing damage during extreme rock crawling situations. The larger bearing contact area spreads impact loads more effectively.
• Can I adjust the caster angle on these axles? — Yes, the kit features adjustable caster geometry, allowing you to fine-tune your vehicle's handling characteristics. More caster angle improves directional stability and self-centering at higher speeds, whilst less caster makes the vehicle more responsive to steering input in tight, technical sections. This tunability is essential for competitive crawlers who need to adapt to different course layouts.
• What makes these portal axles better than standard straight axles? — Portal axles position the gears higher up in the axle housing, which directly translates to increased ground clearance between the chassis and the ground. This is the key advantage over straight axles. Additionally, this kit features all metal gears, 24 ball bearings, steel pivot balls, and aluminium steering plates—all premium components that enhance durability and performance compared to basic alternatives.
